Answer: b) $43,650
Step-by-step explanation:
Contribution margin of Domestic division + contribution margin of Foreign division - traceable fixed cost - common fixed cost = Net operating income for company
46,400 + (0.35 * 243,000) - 51,000 - Common = 36,800
80,450 - Common = 36,800
Common = 80,450 - 36,800
= $43,650
